摘要
Based on the soil geochemical data obtained by multi-purpose regional soil geochemical survey and the data of the second soil survey in Anhui Province,this paper studies the distribution characteristics of soil organic carbon storage,organic carbon density and temporal-spatial variation regulation of soil organic carbon storage in Chuzhou area.The results show that the soil organic carbon storage of the Chuzhou area has reduced for 8.39 Mt in recent 30 years.Soil carbon storage shows a "carbon source" effect in most areas and a "carbon sink" effect in some areas.In Chuzhou area,soil organic carbon storage is 53.74Mt and average organic carbon density is 3.42 kg/m2 in 0～0.2 m surface soil layers,which are slightly lower than the national average levels.In 0～1.8 m surface soil layers in this area,most of the soil organic carbon storage occurs in 0～1.0 m surface soil layers.By analyzing soil organic carbon storage and organic carbon density for different statistical units in Chuzhou area,the paper systematically studies the distribution characteristics of soil organic carbon and provides some references for researching the soil organic carbon cycle.
